Workbench event store

Product: Context Workbench

Workbench treats the case as an append-only stream. The current screen is a projection of that stream, not the source of truth.

Shape

• Events are appended. They are not updated in place.
• A change feed builds the projections the workspace reads.
• A projection can be rebuilt from the stream. The stream cannot be rebuilt from a projection.

This is the architecture the engineering notes describe: an event store with change-feed projections, so a lagging screen is a projection problem, not a lost decision.
